This past weekend on a drive, my vacuum system failed and I was barely able to get enough pressure on the brakes to stop the car. I had recently replaced the relay in the system, as I had seen problems before. After putting in the new relay, things worked fine, for a while. Thinking the switch might be bad, I replaced that as well after the experience last weekend. I tried it tonight and even with the new switch, no luck. I've hooked the vacuum pump up directly to the battery and it runs fine, so I don't suspect the pump. I also moved the power supply to another free ignition source on the fuse box. Nothing is working. Is anyone familiar with this system that could give me some advice? Is it an option to pull vacuum straight off the intake? The car has a performance cam (installed by previous owner), so I'm not sure how much vacuum there will be, but I can't imagine it being worse than the current situation.
